If I create an optical fiber out of diamond (n = 2.49) and want to test it in air (n=1); what is the critical angle to ensure total internal reflection ?
If I create an optical fiber out of diamond (n = 2.49) and want to lost it in air (nr 1), what is the critical angle to ensure total internal reflection?
An optical fiber is constructed out of an inner glass fiber with an index of refraction of 1.62 and an outer plastic coating with an index of refraction of 1.44. Find the critical angle for total internal reflection in this fiber.
1. (20pts) A figure shows a light ray entering an optical fiber from air and being transmitted through the fiber by total internal reflection. A. (10 pts) If the index of refraction of the fiber is nu 1.3 what is the maximum value of the angle the entering ray makes with the normal to the flat end of the fiber, for which total internal reflection occurs? B. (10 pts) When n is greater than a certain value, no, the light...
Problem 33 A laser beam is introduced into an optical fiber, as shown in the figure. In order to ensure the beam to have a total internal reflection r inside the fiber, what is the maximum possible incident angle ? n-1 A) 67.3° B) 121 C) 23.2° D) 56.8 E) 78.5° Optical fiber
The core of an optical fiber has an index of refraction of 1.29, while the index of refraction of the cladding surrounding the core is 1.17. What is the critical angle for total internal reflection at the core-cladding interface? critical angle:
The core of an optical fiber has an index of refraction of 1.27 , while the index of refraction of the cladding surrounding the core is 1.15. What is the critical angle for total internal reflection at the core‑cladding interface?
(2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...
A ray of light enters one end of an optical fiber with an angle of incidence θi = 50.0◦. The index of refraction of the fiber is 1.62. a. Find the angle θ the ray makes with the normal when it reaches the curved surface of the fiber. b. Show that the ray inside the fiber is undergoing total internal reflection. Why would you want this inside an optical fiber? θ
Show all work and explain fully and clearly I want to create a demonstration to show both refraction and reflection (caused by total internal reflection). At what angle must the light hit the water-glass boundary to ensure total internal reflection at the glass-air boundary? Draw the path the light takes as the ray passes completely through the layers. Calculate all relevant angles and label all incident, refracted, and reflected angles. water glass (n = 1.45) air
